Unpublished paper, 'An attempt to form double salts of nitrate of silver and other nitrates' by W J [William James] Russell and [Mervyn Herbert] Nevil Story-Maskelyne

Description

The authors explain that when a solution containing silver and potassium nitrates in equivalent proportions is evaporated, the potassium nitrate separates out, uncombined with silver nitrate. If, however, the ratio of silver nitrate to potassium nitrate is increased beyond a certain limit (which has been determined), then a true double salt having the composition AgNO3 KNO3 crystallises out. The same salt can also be formed from a solution that would not yield it under ordinary circumstances, by either adding nitric acid or by increasing the temperature of the solution, both these alterations tending in the same direction, viz. to decrease the amount of silver nitrate as compared to that of potassium nitrate which can exist in solution.
